摘要
对凹槽梁试样动态应力强度因子现有的几种计算方法进行了分析对比。在此基础上,考虑冲击速度、试样的转动惯性和剪切变形对动态应力强度因子的影响。
In this paper,the methods used for calculating the dynamic stress intensity factor of a notched beam are analyzed briefly.Based on these analyses,a new formula to calculate dynamic stress intensity factor is derived,which takes account of the effects of impact velocity,rotator inertia and shear deformation.
